Definitions
- the present invention relates to proteins having anti-angiogenic activity, the nucleic acids encoding them, as well as pharmaceutical compositions comprising them.
- Angiogenesis is a process of growth of new blood capillaries from pre-existing vessels. Three particular phenomena are in particular at the base of this process: the proliferation, migration and differentiation (tubulogenesis) of endothelial cells.
- Angiogenesis is activated by certain growth factors, known as angiogenic factors, such as NEGF (Vascular Endothelial Growth Factor), FGF-1 (Fibroblast Growth Factor 1, fibroblast growth factor 1) or FGF-2 (Fibroblast Growth Factor 2, fibroblast growth factor 2).
- NEGF Vascular Endothelial Growth Factor
- FGF-1 Fibroblast Growth Factor 1, fibroblast growth factor 1
- FGF-2 Fibroblast Growth Factor 2, fibroblast growth factor 2
- angiogenesis is also involved in many pathological cases, such as diabetic retinopathy, psoriasis, rheumatoid arthritis, age-related macular degeneration, and cancers.
- pathological cases such as diabetic retinopathy, psoriasis, rheumatoid arthritis, age-related macular degeneration, and cancers.
- tumor growth is greatly favored by the appearance within these tumors of a blood neovascularization resulting in particular from the secretion by tumors of angiogenic factors.
- Many attempts at therapeutic treatments based on the use of anti-angiogenic proteins are in progress.
- endostatin O'Reilly et al, Cell (1997) 88: 277-285
- Endostatin is a 20 kDa protein corresponding to a fragment of collagen XNIII.
- the anti-angiogenic activity of this protein is due to a specific inhibition of endothelial cells.
- One of the main drawbacks related to the use of these proteins as anti-angiogenic agents lies in the quantities necessary for the treatment of an individual. Thus, it has been estimated that in the case of endostatin up to several grams of recombinant protein should be administered to the patient each day (Cao, Int. J. Biochem. Cell Biol (2001) 33: 357-369). This drawback could be eliminated, for example, by having more potent angiogenesis inhibitors.
- Fibronectin is a fibrous protein that makes up the extracellular matrix (Hynes (1990) in Fibronectins (Springer, New York)). Some fragments derived from this protein also appear to have anti-angiogenic activity (Yi & Ruoslathi, Proc. Natl. Acad. Sci. USA (2001) 98: 620-624) and other fragments to inhibit endothelial growth in vitro (Homandberg et al., Am. J. Pathol (1985) 120: 327-332). However, in certain cases it has been possible to show that other fibronectin fragments favor the adhesion of metastatic cells to the extracellular matrix (Mold & Humphries, EMBO J. (1991) 10: 4089-4095).
- the object of the present invention is to provide compounds having an anti-angiogenic and / or anti-tumor activity which may in certain cases be greater than those of the anti-angiogenic compounds of the prior art.
- the present invention relates to the use of a peptide sequence comprising or consisting of: - a sequence extending at least from the residues: - 275 to 366 (SEQ ID NO: 4), and / or - 367 to 455 ( SEQ ID NO: 6), and / or - 456 to 531 (SEQ ID NO: 8), of SEQ ID NO: 10, and at most a sequence corresponding to SEQ ID NO: 10, or - a derived sequence sequences defined above by insertion, deletion or mutation of at least one amino acid, provided that said peptide sequence has a binding activity to factor FGF-2, or - a sequence having a homology of at least 85% with one of the sequences defined above, provided that said peptide sequence exhibits factor FGF-2 binding activity
- SEQ ID NO: 10 corresponds to amino acids 1447 to 1991 of the fibronectin peptide sequence (SEQ ID NO: 2) (reference P02751 from the SwissProt database) encoded by the nucleotide sequence SEQ ID NO: 1.
- SEQ ID NO: 4 corresponds to amino acids 1721 to 1812 of fibronectin
- SEQ ID NO: 6 corresponds to amino acids 1813 to 1901 of fibronectin
- SEQ ID NO: 8 corresponds to amino acids 1902 to 1977 of fibronectin.
- the peptide sequences of the invention have the property of binding to factor FGF-2, in particular to factor FGF-2 of molecular weight 18 kDa, and of inhibiting its functioning.
- the anti-angiogenic activity of the peptide sequences of the invention may be due to the blocking of the action of factor FGF-2, thanks to their bond with the latter.
- the double hybrid binding test can be carried out according to the general methodology described by Van den Berghe et al. (Mol. Endocrinol (2000) Nov, 14 (11), 1709-1724).
- a DNA fragment coding for the factor FGF-2 is introduced into the plasmid pAS2 (Clontech, Genebank access number: U30497) and a DNA fragment coding for the peptide sequences whose binding to factor FGF is to be evaluated.
- -2 is introduced into the plasmid pACT2 (Clontech, Genebank access number: U29899).
- the two plasmids are then introduced into the strain Y 190 of Saccharomyces cerevisiae (Clontech; Harper et al., Cell, 1993; 75: 805-816; Flick & Johnston, Mol. Cell Biol, 1990; 10 (9): 4757- 4769) whose activity / 3-galactosidase is measured.
- Saccharomyces cerevisiae Clontech; Harper et al., Cell, 1993; 75: 805-816; Flick & Johnston, Mol. Cell Biol, 1990; 10 (9): 4757- 4769
- the presence of a / 3-galactosidase activity reflects the existence of a link between said peptide sequence and the factor FGF-2.
- the ELISA binding test can be performed as follows.
- the well walls of a standard microtiter plate are coated with FGF-2 factor.
- the peptide sequences whose binding to factor FGF-2 is to be measured, coupled to a histidine label, are added to the wells in variable concentrations, then a labeled antibody directed against the histidine label is added.
- the amount of antibody per well is then determined using the marker, which can be an enzyme, a chromophore or a radioactive compound.
- the quantity of antibodies per well is representative of the bond between said peptide sequences and the factor FGF-2.
- the term "homology” denotes the percentage of similar amino acids for two peptide sequences aligned amino acid by amino acid, as can be obtained by the implementation of the algorithm defined by Altschul et al, Nucleic Acids Res. (1997) 25: 3389-3402 for example.
- the term “angiogenesis” designates the phenomenon of the formation of new blood vessels from preexisting vessels. This phenomenon notably allows tumor growth. Angiogenesis is under the dependence of angiogenic factors such as factor FGF-2 for example.
- the invention also relates to the aforementioned use of a sequence derived from the sequences defined above by insertion, deletion or mutation of at least one amino acid, and / or having a homology of at least 85% with one sequences defined above, provided that said peptide sequence exhibits anti-angiogenic activity and or anti-tumor activity.
- anti-angiogenic activity denotes an activity of inhibiting angiogenesis.
- This activity can, for example, be demonstrated in vitro by demonstrating the inhibition of both the multiplication, migration and tubulogenesis of endothelial cells by the peptide sequences of the invention.
- the measurement of the inhibition of the multiplication of endothelial cells can be carried out by culturing endothelial cells in the presence of the peptide sequence whose activity it is desired to evaluate.
- the measurement of the inhibition of the migration of endothelial cells can be carried out by carrying out a “wound” on a carpet of endothelial cells and then incubating the cells in the presence of the peptide sequence to be tested. The number of cells that have migrated to the wound is then measured.
- the measurement of the inhibition of tubulogenesis of endothelial cells can be carried out by measuring the length of tubules formed by endothelial cells cultured on gel in the presence of the peptide sequence to be tested.
- anti-tumor activity denotes an activity which makes it possible to inhibit tumor growth and / or to induce regression or even the disappearance of tumors. This activity can for example be demonstrated in vivo by measuring the mass of tumors, the development of which has been induced in mice by injection of tumor cells, in the presence and in the absence of administration of peptide sequences of the invention and / or nucleic acids expressing the peptide sequences of the invention.

- the double-hybrid cloning and expression system was carried out as described by Van den Berghe et al. Mol. Endocrinol (2000) Nov, 14 (11), 1709-1724. Briefly, the 18 kDa form of factor FGF-2 was used as bait, and the corresponding cDNA was inserted into the vector ⁇ AS2 (Clontech).
- a human placenta bank (Clontech, Palo Alto, CA) cloned into the vector pACT2 (Clontech) was screened in strain Y 190 (Clontech) of Saccharomyces cerevisiae.
- fragment A One of the cloned fragments, fragment A, has a size; of 1593 base pairs and codes for a fibronectin fragment of 531 amino acids while fragment B of 798 base pairs codes for a fragment of 266 amino acids, which has been named fibstatin (Fib).
- Fb fibstatin
- fragments derived from clone B were generated by PCR, cloned in the plasmid pACT2 and tested in double hybrid as described above.

- the fibstatin subfragment D therefore appears to carry the FGF-2 binding activity. Furthermore, it is conceivable that in vivo the fragment E has; a binding activity to FGF-2 following a proteolytic cleavage, on the contrary it also seems possible that the fragments C, F and G can associate with another protein fragment to reconstitute an active fragment.
- FGF-2 In order to verify the specific interaction of FGF-2 with fibstatin, the interaction of this fragment with other members of the FGF family: FGF-1, FGF-3 and FGF-6, was tested in double hybrid.
- FGF-1, FGF-3 and FGF-6 the cDNAs coding for different members of the FGF family and fibstatin were fused to the DNA binding domain (DB) or to the activation domain (AD) of Gal4 and co-transfected in yeast. Intensities interactions evaluated by measuring the ⁇ -galactosidase activity revealed that fibstatin interacted specifically with FGF-2.
- the fibstatin coding sequence was amplified by PCR from the plasmid pACT2 containing the fibstatin cDNA isolated by the double-hybrid screening.
- the sense primer was 5'-AAACTCGAGACCATGGGAACCCAGTCCACAGCT-3 '(SEQ ED NO: 31) and the antisense primer 5'-AAAGGATCCTTACTTCAGGGCAATGACATA-3' (SEQ ID NO: 32).

- the coding sequences of fibstatin and endostatin were then inserted into the plasmid pET-15b (Novagen) in phase with the histidine tag for the production of recombinant proteins in Escherichia coli, to give the plasmids pET-Fib and pET -Endo.
- the fibstatin and endostatin cDNAs have also been cloned into the eukaryotic expression vectors, pUHD10-3 (Grossen & Bujard, 1992, PNAS (1992) June 15; 89 (12) 5547-5551) to form pUHD -Fib and pUHD-Endo, and pSCT (Prats, 1992, Mol.

After the last wash, the beads were placed on a Polyprep chromatography column (Biorad) and eluted with fractions of 500 ⁇ l of Buffer C containing 200 mM imidazole. The presence of protein was verified by assay of Bradford (BioRad 500-0114, California) and SDS-PAG ⁇ followed by staining with Coomassie blue.
- the cDNAs coding for fibstatin and endostatin fused with 6 histidines were cloned into a vector allowing their expression and their secretion by the Baculovirus system.

- the plasmid expressing it was electrotransferred in vivo to mice carrying B16 melanomas.
- mice Female C57B1 / 6 mice anesthetized by intraperitoneal injection of ketamine (150 mg / kg) received a subcutaneous injection of 10 6 B16 tumor cells in 100 ⁇ l of PBS (incubation time: approximately 10 minutes before injection of the plasmids ).
- 50 ⁇ g of plasmid (5 ⁇ g of LacZ plasmid + 45 ⁇ g of pSCT Fib ( Figure 8), pSCT Endo or pSCT) prepared using the Maxiprep Endofree kit (Qiagen, France) and diluted in 50 ⁇ l of PBS were injected into the quadriceps of mice with a 26G 0.45x10 syringe.
- the injected plasmids were then immediately electro transferred by two electrodes of 10 mm in diameter, separated by 4 mm, in contact with the skin using an ElectroSquare Porator ECM830 device (BTX, Genetronics, San Diego, CA) by 8 pulses of 20 ms at 80V.
- the efficiency of electroporation was favored by the use of an ultrasound gel applied to the paw.
- the injection followed by the electrotransfer of the plasmids was restarted 5 days later. 10 days after the first injection, the tumors and electro transferred muscles were recovered and weighed. The muscles were then lysed in 350 ⁇ l of ⁇ -Gal lysis buffer (Tropix) and homogenized using an ultra-turax (Polylabo).
- the suspension was centrifuged at 13,000 rpm for 10 min.
- the assay for ⁇ -galactosidase activity was then carried out on 20 ⁇ l of supernatant using the Galacto Light TM kit (Tropix).
- the mouse serum was also recovered using Capiject tubes (Terumo) containing a silica gel facilitating the recovery of the serum.
- the circulating endostatin was assayed using the Mouse Endostatin Accucyte ELISA kit (Cytimmune).
- mice having received an injection of the plasmid pSCT-Fib have a tumor mass reduced by half compared to the mice injected with the control plasmid.
- the mice having received an injection of the plasmid pSCT-Endo also exhibit a decrease in their tumor mass but statistically insignificant (FIG. 10). The results were obtained using 14 mice per group.
- tumor capillaries were examined by anti-CD31 immunostaining. Briefly, the density of the tumor microvessels was analyzed on frozen sections (5 ⁇ m) of B16 melanomas using an anti-mouse CD31 rat monoclonal antibody (Pharmingen, San Diego, CA). After fixing in paraformaldehyde for 1 h at 4 ° C., the sections were washed 3 times with PBS and were permeabilized using a PBS-0.25% Triton X100-3% SAB mixture for one hour.
- FIG. 12A representative sections of mouse tumors treated with fibstatin and endostatin show a significant decrease in labeling of CD31, in comparison to sections of control mouse tumors. Quantification of microvessels at 200-fold magnification indicates that the CD31 labeling positive surface in tumors of control mice was 2.2% ⁇ 0.58 (mean ⁇ standard deviation), compared to 0.74% ⁇ 0.58 and 0.94% ⁇ 0.58 for tumors treated with fibstatin and endostatin respectively (Figure 12BV Together, these results demonstrate that the transfer of the fibstatin gene inhibits the angiogenic response in vivo.
